Install firebase and angularfire2 error


i want to build a chat app, and using the firebase with ionic 2.

`npm install firebase angularfire2 --save`

it shows an error unmet peer dependency rxjs@5.0.0-beta.12


Not sure but this might be similar to the issue I had here

You don’t need to install Firebase. AngularFire now contains the Firebase module so I expect you have it defined twice in your project.


thank for your reply, does that mean i do not need install firebase and angularfire 2 for ionic ? ionic 2 has them included already ?


You just need to install AngularFire not Firebase AND AngularFire.
